Maybe the factory endlinks are exceptionally durable for your needs. Not for our's.

If they are good enough for you, or Pedders, then that’s great. But testing on trucks and SUVs realistically isn’t “apples to apples” compared to testing on a Camaro that is trying to sqeak out another .5 seconds on an Auto-X course. It is really not even up for debate that an endlink bushed with polyurethane bushings and a composite sleeve is significantly more compliant than an endlink that uses rigid OEM style ball joints and an aluminum turnbuckle. We chose to replace the endlinks because “the difference between ordinary and extraordinary, is that little extra” . We initially designed and tested a swaybar that re-used the OE endlinks. That was the most affordable way to go for us, and for customers. The bar wasn’t bad, but it wasn’t great. We weren’t willing to let such a nice swaybar suffer from inferior endlinks. We then tested the design we just released for sale and were amazed at how much more stable the car felt upon initial turn-in and how much quicker the suspension settled down after a turn. That attribute was all due to the endlinks not squishing and flexing. We feel our product performs great and is a great value.

This is why I modified my rear endlinks to be stiffer than stock, the stock plastic stalks still flex even in my own hands, my homemade .5" pipe tube setup is way stiffer and responsive but yes like the Pedders guy said those black hard rubber factory pieces are pretty stiff like sun hardened chewing gum along with the half inch pipe they are as stiff and yet rattle free even compared to the previous bars with heim joints and stuff with a tad bit more comfort. The stock plastic stalks gotta go sorry Pfadt. LSR it is good to see you have endlinks that have that setup great job.
